Description

[Detailed explanation of the idea] (Industrial application field) The present invention is a dispute regarding a gutter joint device.

(Prior Art) Conventionally, when rainwater from an entrance porch or rainwater from an eaves gutter is drained by penetrating the ceiling surface, a drain pipe 4' is used to penetrate the roof 5' as shown in FIGS. 4 and 5. A gutter body 3' such as a gutter joint or a vertical gutter was fitted and bonded to the drain pipe 4'.

(Problem that the invention aims to solve) However, once the gutter body 3' is fitted and glued to the drain pipe 4', it cannot be removed, so if the gutter body 3' is damaged and needs to be replaced, it is necessary to cut the gutter body 3'. There was a drawback that the connection had to be made again.

Furthermore, if the drain pipe 4' and the gutter body 3' are made of different materials, it may be difficult to bond them, and the drain pipe 4' and the gutter body 3'
If the fit is loose, there is a drawback that connection cannot be established.

The present invention eliminates the drawbacks of such fitting adhesive type vertical gutter joints, and provides a gutter joint device that can connect the drain pipe and the gutter body even if the fit is loose without using adhesives. This is what we are trying to provide.

(Means for Solving the Problems) The present invention provides a locking tube 1 having a male threaded portion 11 on the outer circumferential surface and a female threaded portion 21 on the upper inner circumferential surface of the drain pipe 4 penetrating the ceiling surface and hanging down. The locking tube 2 is screwed into the locking tube 2, and the locking tube 2 is provided with a circumferential groove 22 below the female threaded portion 21, and an annular elastic body 23 is fitted into the circumferential groove 22. 23 is fitted onto the outer periphery of the drain pipe 4, and the lower end of the locking tube 1 is inserted into the circumferential groove 2 at the end of the screw engagement between the locking tube 1 and the locking tube 2.
As a result, the lower end of the locking cylinder 1 presses the elastic body 23 to reduce the inner diameter of the elastic body 23, and the elastic body 23 is brought into close contact with the drain pipe 4. A locking edge 24 is provided at the lower end of the locking cylinder 2,
This relates to a gutter joint device in which a collar 31 provided at the upper end of the gutter body is engaged with this locking edge 24.

The present invention will be explained below with reference to the drawings.

FIG. 1 is an exploded perspective view showing the locking tubes 1 and 2 used in the present invention. A circumferential groove 22 is provided below the female threaded portion 21, and an elastic body 23 is fitted into the circumferential groove 22, and the elastic body 23 is fitted onto the outer periphery of the drain pipe 4.

The lower end of the locking tube 1 reaches below the upper end of the circumferential groove 22 at the end of the screwing engagement between the locking tube 1 and the locking tube 2, so that the lower end of the locking tube 1 presses the elastic body 23. The inner diameter of the elastic body 23 is made small so that the elastic body 23 is brought into close contact with the drain pipe 4.

The elastic body 23 may be made of elastically deformable rubber, synthetic resin, or the like, but it is particularly preferable that the elastic body 23 has a concave curved surface on its outer surface and a curved cross-sectional shape.

An inward locking edge 24 is provided at the lower end of the locking tube 2 .

Further, a folded edge 12 is formed at the upper end of the locking cylinder 1.

A gutter joint 3 is used as the gutter body.

4 is a drain pipe that penetrates the ceiling surface of the roof and hangs down.

The collar 31 at the upper end of the gutter joint 3 is engaged with the locking edge 24 of the locking tube 2, and the locking tube 2 is screwed together with the locking tube 1, and furthermore, the locking tube 2 is screwed into the drain pipe 4 from the locking tube 1 side. It is inserted.

When the locking tube 1 and the locking tube 2 are tightly screwed together and reach the screwing limit,
The tip of the locking tube 1 presses the elastic body 23, and the elastic body 23 is pressed toward the drain pipe 4, thereby fixing the gutter joint 3 to the drain pipe 4.

The example in Fig. 2 is a case where the inner diameter of the gutter joint 3 is approximately equal to the outer diameter of the drain pipe 4, but as shown in Fig. 3, the inner diameter of the gutter joint 3 is larger than the outer diameter of the drain pipe 4. Even if there is a gap between them, if the locking tube 1 is screwed together more strongly, the elastic body 23 will protrude inward and press the drain pipe 4 to fix it.

A gutter, a vertical gutter, etc. are connected to the gutter joint 3 to drain rainwater.

(Function) The locking cylinder 1 and the locking cylinder 2 are screwed together by the male threaded part 11 and the female threaded part 21.

The elastic body 23 fitted into the circumferential groove 22 of the locking cylinder 2 is
When the locking tube 1 and the locking tube 2 are screwed together and the tip of the locking tube 1 presses the elastic body 23, the inner diameter is larger than the drain pipe 4. Its inner diameter is reduced, and the elastic body 23 is brought into close contact with the drain pipe 4.

The locking edge 24 is engaged with a collar 31 provided at the upper end of a gutter body such as a gutter joint or a vertical gutter.

When the locking tubes 1 and 2 are screwed together, the upper end of the locking tube 2 is fitted into an annular groove 13 formed by the folded edge 12 at the upper end of the locking tube 1. , the locking tube 1 and the locking tube 2 are easily screwed together.

(Effect of the invention) The present invention has the above-mentioned configuration, and has a locking tube 1 and a locking tube 2.
When the screws are screwed together and the screwing limit is reached, the lower end of the locking tube 1 reaches below the upper end of the circumferential groove 22, and as a result, the lower end of the locking tube 1 presses the elastic body 23 and the elastic body Since the inner diameter of the elastic body 23 is made small and the elastic body 23 is tightly attached to the drain pipe 4, the locking cylinder 1 and the locking cylinder 2 can be firmly screwed together until the screwing limit is reached without using adhesive. The gutter body can be removably fixed by simply doing so, and the gutter body can be easily connected, and if the gutter body is damaged, the part beyond this connecting part can be replaced.

In addition, the gutter bodies such as gutter joints are engaged with and connected to the locking tube 2, and are not directly connected to the drain pipe 4, so the drain pipe 4
Even if there is a gap between the gutter body and the gutter body, the connection can be made.
